We describe an architecture for distributed collaborative visualization that integrates video conferencing, distributed data management and grid technologies as well as tangible interaction devices for visualization. High-speed, low-latency optical networks support high-quality collaborative interaction and remote visualization of large data.
We describe a high-quality collaborative environment that uses High-Definition (HD) video to achieve near realistic perception of a remote site. The capture part, consisting of a HD camera, Centaurus HD-SDI capture card, and UltraGrid software, produces a 1.5 Gbps UDP data stream of uncompressed HD video that is transferred over a 10GE network interface to… (More)
Providing secure, extensible, pervasive and easy to implement collaborative environment for medical applications poses significant challenge for state-of-the-art computer systems and networks. In this paper, we describe such a collaborative environment developed for Ithanet project, based on Grid authentication mechanisms. Significant effort has been put… (More)
—This article describes a distributed classroom experiment carried out by five universities in the US and Europe at the beginning of 2007. This experiment was motivated by the emergence of new digital media technology supporting uncompressed high-definition video capture, transport and display as well as the networking services required for its deployment… (More)
In this paper, we present a framework called CoUniverse, designed for building real-time user-empowered collaborative environments to work primarily on high-speed networks with true high-bandwidth applications such as uncompressed high-definition video. The system is designed for unreliable experimental infrastructures and therefore its operation relies… (More)
The workshop will provide an insight in solving real-world problems using the high-quality, low-latency media transmissions over (high-speed) networks and implemented by the UltraGrid and CoUniverse software developed by CESNET. During the workshop we'll go step-by-step through a deployment of UltraGrid and CoUniverse for a multi-point media transmissions… (More)
The talk will showcase the technology developed by CESNET for very high quality, low-latency media transmissions over high-speed networks and its applications in various fields including medicine, arts, broadcasting and cinematography, sports or education. The talk covers different aspects and demands of such applications and how they can be implemented… (More)
Transfers of high-quality multimedia content pose new demands on capacity and services provided by the contemporary high-speed computer networks. Transfer of stereo-scopic video is a specific example, as it needs synchronization between two separate data streams. We have set up a stereoscopic video capture system and studied synchronization of two separate… (More)
